Acrobat Reader DC version 22.001.2011x (and earlier), 20.005.3033x (and earlier) and 17.012.3022x (and earlier) are affected by an out-of-bounds read vulnerability when parsing a crafted file, which could result in a read past the end of an allocated memory structure. An attacker could leverage this vulnerability to execute code in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file.
Security readout for executives and security teams
Plain-English summary
A malicious document could make vulnerable Adobe Acrobat Reader DC run attacker-controlled code as the signed-in user. The attack requires someone to open the crafted file, so exposure is tied to user workstations and document-handling workflows.
Executive priority
Treat this as a high-priority workstation remediation issue, especially for teams receiving external documents. It is not described as wormable or actively exploited in the provided evidence, but user-assisted code execution creates material business risk.
Technical view
CVE-2022-28243 is a CWE-125 out-of-bounds read in Acrobat Reader DC file parsing. A crafted file can trigger a read past an allocated memory structure and may lead to remote code execution in the current user context. CVSS 3.1 is 7.8 high.
Likely exposure
Organizations are likely exposed where Adobe Acrobat Reader DC versions 22.001.2011x or earlier, 20.005.3033x or earlier, or 17.012.3022x or earlier are installed and users open untrusted files.
Exploitation context
The provided sources do not show CISA KEV listing or active exploitation. Exploitation requires user interaction: the victim must open a malicious file. Impact is high because successful exploitation can affect confidentiality, integrity, and availability under the current user account.
Researcher notes
Evidence is limited to the CVE record and Adobe advisory reference. Do not assume exploitation in the wild, additional affected products, or exact fixed versions from this bundle alone. Validate against APSB22-16 before closing remediation.
Mitigation direction
Check Adobe APSB22-16 for vendor-approved update guidance.
Prioritize remediation on workstations handling external PDFs or email attachments.
Reduce exposure by discouraging opening unexpected or untrusted documents.
Use endpoint and email controls to inspect or block suspicious attachments.
Validation and detection
Inventory installed Adobe Acrobat Reader DC versions across endpoints.
Flag versions at or below 22.001.2011x, 20.005.3033x, or 17.012.3022x.

CWE-125: Exact CWE lookup
Use the exact CWE identifier as the starting point before reviewing related ATT&CK behavior. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
The CVE wording references code or command execution, so execution technique review may help defensive triage. This is a Glexia inferred lookup path, not an official MITRE, ATT&CK, or CVE Program mapping.
These fields come from the CVE record and ADP containers, not from Glexia's Take. They preserve time-varying source decisions such as CISA SSVC, KEV status, CVSS metrics, and provider references.

Out-of-bounds Read
Out-of-bounds Read represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
